The lead author of the report is Charles Helm, a former family physician in Tumbler Ridge, B.C., who is originally from South Africa.

Helm's interest in paleontology began in 2001 when his son and a friend found dinosaur tracks while tubing in Flatbed Creek near Tumbler Ridge, in northeastern B.C. ...

... Over the past few years, he and his family have been exploring the
country's coastline, uncovering tracks from lions, elephants, and
"extinct giant horses," Helm told CBC Daybreak North host Carolina de Ryk.

holy grail": a series of human footprints on the roof of a cave. [...] CBC News
